I'm using Synopsis DC for synthesis.. I get a warning in the multi voltage check report saying that "the isolation cell A connecting pins C (related supply net X) and D (related supply net Y) maybe redundant. Supply net Y is always on or more or less equal to supply net X".. Wat does it mean exactly?? And how to clear this warning??

- - - Updated - - -

And I also want to knw what this warning means "isolation cell does not have any upf isolation strategy." How exactly can we clear this warning???
 

If supply net X and supply net Y belongs to smae power domain then you donot need isolation cell between these domains
 

Is that what the warning says? Should the isolation cell not be there?? Or is it like an error that they are always in the same voltage and so there's something wrong with the isolation cell??
